Gold-198 is not naturally occuring.
Gold-198 is a synthetic isotope that is produced artificially by bombarding gold-197 with neutrons in a nuclear reactor.

118 Neutrons are in the Element Gold.The number of neutrons can vary for an element, but for gold the stable isotope has 118 neutrons.This is gold-197 (197-Au) and includes virtually all naturally occurring gold on Earth.Synthetic radioisotopes of gold are 195-Au, 196-Au, 198-Au, and 199-Au.All atoms of gold have 79 protons, and neutral atoms have 79 electrons.
Gold 198 has 118 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass number (sum of protons and neutrons). In the case of gold, the atomic number is 79, so 198 - 79 = 119 neutrons.
The radioactive isotope 198Au has the mass number 198.

After 4 days, only 1/16 of the original amount of gold (198/16 = 12.375) will remain.

Gold-198 predominantly emits a mono-energetic gamma ray of energy 0.412 MeV. It also emits beta rays of much higher energy than that of gamma rays.
The atomic mass of an element is the weighted average of the masses of its isotopes, taking into account their abundance. If the atomic mass of an element is 197.97, it represents the average mass of all naturally occurring isotopes of that element.
